OKCULAR, Turkey  A strong, pre-dawn earthquake knocked down stone and mud-brick houses, barns and minarets in eastern Turkey on Monday, killing 51 people in five villages, the government said.
The earthquake surprised many residents as they slept, crumpling buildings into piles of rubble. Panicked survivors fled into narrow village streets, some climbing out of windows, as nearly 80 aftershocks measuring up to 5.5 and 5.3 magnitude rattled the region.
The Kandilli seismology center said the 6.0-magnitude quake hit at 4:32 a.m. (0232 GMT, 9 p.m. EST Sunday) near the village of Basyurt in a remote, sparsely populated area of Elazig province. The region is 340 miles (550 kilometers) east of Ankara, the capital.
The U.S. Geological Survey listed the quake at 5.9 magnitude.
The government initially put the death toll at 57 but later lowered it to 51 with no explanation. In addition to the deaths, 34 people were being treated for injuries, Turkey's crisis center said.
The damage appeared worst in the village of Okcular, where at least 15 of the village's 900 residents were killed, the Elazig governor's office said.
As relatives rushed in for news of their loved ones, authorities blocked off the area so ambulances and rescue teams could maneuver up Okcular's narrow, steep roads. Residents lit fires to keep warm in the winter cold, with snow-covered mountains in the background.
"The village is totally flattened," village administrator Hasan Demirdag told private NTV television.
Resident Ali Riza Ferhat said he was woken up by the jolt.
"I tried to get out of the door but it wouldn't open. I came out of the window and started helping my neighbors," he told NTV television. "We removed six bodies."
Video footage showed men using shovels and their bare hands to dig two bodies out from under piles of dirt, rubble and concrete blocks that used to be homes. Both bodies were covered in blankets and carried away. One appeared to be a baby or young child.
Women in veils gathered near the rescue scenes, some crying.
"Everything has been knocked down, there is not a stone in place," said Yadin Apaydin, administrator for the village of Yukari Kanatli, where three people died.
Another 15 people were killed in the nearby village of Yukari Demirci, Gov. Muammer Erol said, four each were killed in the villages of Kayalik and Gocmezler and 10 others died after being taken to a hospital in the town of Kovancilar.
The temblor also knocked down barns, killing many farm animals. A half-dozen dead cows could be seen partially buried in the dirt near one collapsed home.
Prime Minister Recep Tayyip Erdogan and Kandilli Observatory's director, Mustafa Erdik, urged residents not to enter any damaged homes, warning they could topple from aftershocks that Erdik said could last for days.
Erdogan blamed the region's mud-brick buildings for the many deaths and said the government housing agency will build quake-proof homes in the area. He said ambulance helicopters, prefabricated homes and mobile kitchens were being rushed in, and Turkey's Red Crescent aid group sent tents and blankets.
The quake was also felt in the neighboring provinces of Tunceli, Bingol and Diyarbakir, where residents fled to the streets in panic and stayed outdoors. Schools were closed for two days in the region. In Tunceli province, students were sent home after the quake caused a school's walls to crack, the state-run Anatolia news agency reported.
A museum in Elazig displaying artifacts from the Iron-age Kingdom of Urartu was not affected by the quake, and nearby dams were also intact.
Earthquakes are frequent in Turkey, much of which lies on top of two main fault lines. In 1999, two powerful earthquakes struck northwestern Turkey, killing about 18,000 people. In 2003, a 6.4-magnitude earthquake killed 177 people in Bingol, including 84 children whose school dormitory collapsed.
The Elazig quake followed deadly temblors in Haiti and Chile, but Bernard Doft, the seismologist for the Royal Netherlands Meteorological Institute in Utrecht, said there was no direct connection between the three.
"These events are too far apart to be of direct influence to each other," he said.
Richard Luckett, a seismologist from the British Geological Survey, said there has not been a spike in global seismic activity.
"If there was a big increase in the number of magnitude 6.0s in the past decade we would know it because we would see it in the statistics," Luckett said. "We haven't seen an increase in 7.0s either."
He said scientists often see strong quakes but they don't get reported because the damage or death toll is minimal. According to USGS data, the world is hit by about 134 earthquakes a year in the 6.0- to 6.9-magnitude range  or about two a week.
"The point is that earthquakes are common and always have been," he said.
